Abstract (en)

An intraocular lens injection instrument (1) for injecting an intraocular lens (100) into an eye, the intraocular lens (100) comprising an optical part (110) of a disk-like shape and a first support part (112A) extending outwardly from an outer circumferential part (110a) of the optical part (110a). The intraocular lens injection instrument (1) comprises: a passage (20b) having a passage area gradually decreasing toward a tip end (20a) of the intraocular lens injection instrument (1); inner wall surfaces (20c) formed on both sides in a direction orthogonal to an axial direction of the passage (20b), the direction being parallel to a radial direction of the optical part (110) when the intraocular lens (100) is placed in the passage (20b); a push member (12) configured to push out the intraocular lens (100), the push member including a contact portion (12a) to be placed in contact with the intraocular lens (100); and a lens control mechanism to control an orientation of the intraocular lens (100) in a circumferential direction of the optical part (110). The lens control mechanism is configured to direct movement of the contact portion (12a) of the push member (12) toward one of the inner wall surfaces (20c) when or after the intraocular lens (100) with the first support part (112A) positioned ahead of the optical part (110) toward the tip end (20a) in the passage (20b) is pushed toward the tip end (20a) by the push member (12) and then the first support part (112A) is folded so that a distal end portion (118A) of the first support part (112A) is disposed more inward than the outer circumferential part (110a) of the optical part (110).
